Remove the instrument cluster, (speedo, revs etc). On the back of it, there is usually two holes, one with a screw and one with out (sometimes it will say, "T-belt" near it. All you do is take the screw out and put it in the other hole. This works for most Hiaces

To reset the timing belt light on a 1998 Toyota Hiace van, first, turn the ignition switch to the "ON" position without starting the engine. Then, locate the trip meter reset button on the dashboard.

If you have already replaced the belt and the light is still on you will need to remove the lower and upper dash panels and then remove the instrument cluster which holds your speedometer and other devices. The reset button for the timing belt light is behind the cluster.

There are several ways to rest this light that all involve some level of dismantling your dashboard, the differences are based on the equipment package and the year of the vehicle. I'm hesitant to answer in detail because based on your vehicle specifics I may give you the info for the wrong model, so here is a quick answer; One method involves moving the "timing belt screw" behind the instrument cluster from one position to another (it is marked and will be obvious when you see it) Another involve pushing a pin through a rubber grommet on the instrument cluster to reach a reset button, while another still is an electronic reset you can do with the trip meter reset on your instrument cluster. The steps to remove the dashboard, if necessary for your car vary by model since the cluster will be different. Do a google search for Toyota hiace forum, then search timing belt reset. The good news,the Toyota hiace owners forum covers this in detail, with pictures and a detailed discussion that i could not fit here. When you find the information pertaining to your specific model, please share with others. Good luck
